Electric Vehicles are vehicles that operate entirely or partially on electric motors, utilizing electrical energy stored in batteries or other rechargeable energy storage sources. The increasing use of electric vehicles also brings potential risks of new types of accidents, different from those associated with conventional internal combustion engine vehicles. Therefore, there is an urgent need to provide accurate information and appropriate handling related to electric vehicle technology, including hazard potential assessment, optimization of firefighting basics, selection of suitable firefighting agents, and the development of electric vehicle firefighting application methods. This study aims to understand the handling of electric vehicle fires using a literature review method on 10 research articles. The results show that 6 studies used water as a firefighting agent either alone or in combination with other agents such as CO2, C₆F₁₂O, liquid nitrogen, foam, and fire blankets, making it more effective in extinguishing electric vehicle fires. However, one study does not recommend using water due to its environmental impact when extinguishing electric vehicle fires. The research findings indicate the need for further innovation and research in safety technology and firefighting for electric vehicles.

Boarding homes are very crucial for students who live far from home, especially for those who go to Perbanas Institute.  Choosing a boarding home has frequently been done without a defined procedure, which has made it hard for students to identify alternatives that fit their needs and budget.  This study creates a web-based decision support system (DSS) for choosing boarding homes based on the Simple Additive Weighting (SAW) technique.  This technique gives each criterion price, distance to campus, facilities, security, and room size weights. These weights are then used to find the best option from the 10 available by normalizing and ranking them.  Surveys, observations, and reading books were used to gather research data. The weights were then set depending on what the students wanted.  The results of the calculations reveal that "Kost Evi" got the highest score, hence it is the best pick.  The system that was created can make decisions faster and easier, and it does it in a way that is clear and accurate.  This technique may also be used in a number of different multi-criteria decision-making situations, making it a useful and adaptable option for more organized decision-making needs...

This study focuses on solving the green economic load dispatch problem by considering the presence of green energy sources, including wind energy and solar power plants. The main objective function of the whole study is to minimize the total fuel cost (TFC) of all the thermal generating sources (TGSs) in the system. Moreover, the multiple selection of all TGSs is also evaluated. Fire hawk optimization (FHO) and the Zebra optimization algorithm (ZOA) are applied to solve the problem of achieving the best TFC value and satisfying all the constraints involved. The results indicated that ZOA can achieve a better optimal solution compared to FHO. Particularly, the results obtained by ZOA are completely superior to FHO in all comparison criteria at two load demand levels, such as Best TFC value (Best.Cost), Average TFC value (Aver.Cost), and Maximum TFC value (Max.Cost). On top of that, ZOA is the only algorithm of two applied ones providing the fast convergence capability to the optimal value of the main objective functions in two cases of load demand levels. Therefore, ZOA is an efficient search method to deal with such GELD problems.

This paper proposes a method based on the Lagrange optimization function and local search technique for minimizing the total cost of two power systems. The first system comprises ten multiple fuel thermal units (MFTUs) while the second system combines the first system with renewable energies, solar and wind power. The proposed method has advantages over its conventional method without a local search technique, called the conventional Lagrange function-based method (CLM), such as having the same parameters and exploiting other search spaces after getting convergence. The proposed method is more effective than CLM for the first system with the last case of load demand. In addition, the proposed method has better costs than previous algorithms, such as the Hierarchical numerical method (HNUM), Hopfield neural network, Adaptive Hopfield neural networks (AHNN) and modified Lagrange neural network (MLANN). Especially, the proposed method can find smaller costs than them, up to $6.78, corresponding to 1.4% for Case 1, and up to $2.43, corresponding to 0.4% for Case 4. Only the proposed method is tested on the second test system. The simulation results indicate that the method is very efficient for the problem with solar and wind energies and multiple fuel thermal units.
